CROSS REFERENCE TO RELATED APPLICATION

This application is a continuation of U.S. Ser. No. 15/964,053, filed on Apr. 26, 2018, pending, and entitled “RECYCLABLE BUILIDNG BLOCK AND BUILDING SYSTEM USED FOR CONSTRUCTING BUILDING”, which is a continuation-in-part of International Application No. PCT/CN2017/000151, filed Feb. 10, 2017 designating the United States and claiming priority with respect to Chinese Patent Application No. 201610098785.X, filed Feb. 17, 2016, entitled “ENVIRONMENTALLY FRIENDLY BUILDING KIT”, the the disclosures of both foregoing applications being incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates to building material, and more particularly to a recyclable building system used for constructing a building.

BACKGROUND ART

Generally, a solid waste involved in the present disclosure includes: industrial solid wastes, domestic wastes, construction wastes, urban sludge, and crop straw wastes. The industrial wastes include, but not limited to, a waste slag, a slag and corner wastes of industrial products. The domestic wastes include, but not limited to, waste papers, waste furniture, used plastic, packaging materials and surplus deteriorating foods, which are produced in daily life. The construction wastes include, but not limited to, cement blocks, bricks and decoration materials produced while old buildings are demolished. The urban sludge includes, but not limited to, sludge produced by sewage treatment, sludge excavated in urban underground projects, and sludge deposited in urban sewage all year round. The crop straw wastes include, but not limited to, rice straw, wheat straw, corn stalk, sorghum stalk, cotton straw, peanut straw, sesame straw, and rape straw. At present, there are many methods to deal with these various types of wastes. However, with the continuous development of the society, the various types of wastes have not been handled well and become increasingly serious social problems and continue to cause harm to the human living environment.

At the same time, various methods for constructing walls are using cement mortar to block bricks into walls, or after the frame structure is built, the wall plates are fixed to the frame structure. These methods must be implemented by professional staff using professional tools and equipment. And the built walls are all base blank walls without any decoration. After the wall is built, if it needs to be renovated and decorated, the building material used for building the wall cannot be used repeatedly for construction and demolition. As a result, a large amount of building materials is wasted, and the disassembled construction waste cannot be decomposed and become new solid wastes, causing environmental pollution.

Therefore, a new recyclable building system needs to be provided.

As shown in FIG. 1 through FIG. 7, as well as FIGS. 15-17, a building system 1 according to a first embodiment of the present disclosure is used for constructing a building 900. The building system 1 including a plurality of building blocks is mounted on a flat foundation 901 to construct the building 900. The building system 1 includes a normal block 11 used at a normal position 904 while constructing the building 900, a corner block 12 used at a corner position 903 while constructing the building 900, and a connection block 13 used to fill the gaps 902 created while constructing the building 900, such as one or two points of a termination. The normal block 11, corner block 12 and the connection block 13 may interlock with each other to construct the building 900.

The normal block 11 is substantially cuboidal-shaped block structure for constructing the building 900. The normal block 11 includes an inner face 110, an outer face 111 opposite to the inner face 110, an upper face 112, a lower face 113 opposite to the upper face 112, a first end 114 and a second end 115 opposite to the first end 114. The inner face 110 and outer face 111 are substantially planar faces. The outer face 111 and inner face 110 may be a smooth face or a patterned face. At least one of the outer face 111 and the inner face 110 may be decorated as desired. Alternatively, the building block 11 may include a decorative face attached to at least one of the inner face 110 and the outer face 111. The decorative face can be decorated with multiple colors or colored patterns by means of printing, molding, filming, engraving, pasting or hand-painting. The pattern may be flat or three-dimensional wood grain, stone grain, brick grain, skin grain. The pattern may be people, photos, geometry, logo and so on. Alternatively, the decorative face may be integrally formed with at least one of the outer face and inner face.

The upper face 112 has a base face 1121 and a projection 1122 protruding upwards from the base face 1121. The projection 1122 is disposed at a center of the upper face 112 and extending longitudinally for the entire length of the upper face 112. The projection 1122 is generally trapezoidal shaped in cross sectional configuration. Specifically, the projection 1122 has a pair of guiding faces 1122 a opposite to each other and a top face 1122 b connected between the guiding faces 1122 a. Each of the guiding faces 1122 a extends inclined from the base face 1121 for preventing water from flowing into the building block, i.e. the guiding face 1122 a of the projection 1122 is connected with the base face 1121 of the upper face 112 at an angle β. The angle β may be greater than 90 degrees and smaller than 180 degrees. With the configuration of the guiding face 1122 a, the blocks stacked upon each other can be well positioned and guided to interlock with each other.

The lower face 113 is substantially complementary to the upper face 112. Specifically, the lower face 113 has a complementary groove 1131 for receiving the projection 1122 of a cooperating block when the blocks stacked upon each other to form an interlocking bond, wherein the cooperating block is similar to the normal block 11. In the present disclosure, a depth d of the groove 1131 is greater than a height h of the projection 1122 in a vertical direction Z so that a horizontal through hole 14 is formed by the projection 1122 of one normal block 11 mating with the groove 1131 of the cooperating block when the blocks stacked upon each other, wherein the cooperating block is identical or similar to the normal block 11. The horizontal through hole 14 may be used for receiving electrical wires, pipes or other utility.

The normal block 11 further includes a plurality of first through holes 101 disposed in the projection 1122 and extending from the top face 1122 b of the projection 1122 to the lower face 113 of the building block 11. The plurality of first through holes 101 are arranged spaced-apart with each other at an equal interval. The first through hole 101 may be cuboidal shaped, cylindrical-shaped, and the like. The design of a plurality of first through holes 101 facilitates in the formation of a first vertical channel, when a plurality of blocks, similar to normal block 11, are stacked upon each other.

The normal block 11 further includes a plurality of third through holes 102 disposed in the projection 1122 and extending from the top face 1122 b of the projection 1122 to the lower face 113 of the building block 11 for receiving electrical wires, pipes or other utility. The plurality of third through holes 102 are arranged spaced-apart with each other at an equal interval. Each third through hole 102 is located between two adjacent first through holes 101. The third through hole 102 may be cuboidal shaped, cylindrical-shaped, and the like. A diameter of the third through hole 102 is smaller than that of the first through hole 101. Alternatively, the diameter of the third through hole 102 may be equal to the first through hole 101.

The first end 114 has a tongue 1141 formed at a center thereof. The tongue 1141 protrudes outward at the first end 114 of the normal block 11, i.e. protrudes in a direction away from the second end 115. The tongue 1141 extends longitudinally for the entire length of the first end 114. The entire length of the first end 114 is a length of the normal block 11 in a vertical direction Z. The second end 115 has a concave portion 1151 formed at a center thereof. The concave portion 1151 protrudes inward at the second end 115, i.e. protrudes in a direction toward the first end 114. The concave portion 1151 extends longitudinally for the entire length of the second end 115. The entire length of the first end 115 is the length of the normal block 11 in the vertical direction Z. The configuration of the tongue 1141 and the concave portion 1151 is produced such that the tongue of one normal block can interlock with the concave portion of a cooperating block, wherein the cooperating block is identical or similar to the normal block 11.

The corner block 12 has a generally L-shaped outline when viewed from above in FIG. 4. The corner block 12 includes an inner face 120, an outer face 121 opposite to the inner face 120, an upper face 122, a lower face 123 opposite to the upper face 122, a first end 124 and a second end 125. The first end 124 is at right angles to the second end 125. The structure of the corner block 12 is substantially similar to that of the normal block 11. The upper face 122 also has the base face 1121 and the projection 1122 extending for the entire length of the upper face 122 of the corner block 12. The lower face 123 also has the groove 1131. The corner block 12 also has the first through holes 101 and the third through holes 102 formed in the projection 1122 and extending from the top face 1122 b of the projection 1122 to the lower face 123 of the corner block 12.

The first end 124 and the second end 125 both have the concave portions 1151, i.e. the concave portions 1151 protrudes inward at the first and second ends 124, 125, respectively. When a normal block 11 and a corner block 12 are mated adjacent to each other, the interlocking bond is formed. Precisely, when the tongue 1141 of the normal block 11 is mated with the concave portion 1151 of the corner block 12, the interlocking bond is formed due to the complementary nature of the structure between the tongue and the concave portion 1151.

The corner block 12 further includes an avoiding space 129 formed at the corner thereof. The avoiding space 129 includes one or two recesses 1291 formed by means of removing the projection 1122 at the corner. The corner block 12 further includes a protruding portion 128 disposed in a center of the avoiding space 129 and protruding upwards from the base face 1121 of the upper face 112 of the corner block 12. The avoiding space 129 is configured for receiving the lower face 123 of cooperating corner block 12 when the corner blocks 12 stacked upon each other, wherein the cooperation corner block 12 is identical to the corner block 12. A second through holes 1281 is formed in the protruding portion 128 and extending from the protruding portion 128 to the lower face 123 of the corner block 12.

As shown in FIG. 6-7, the connection block 13 has one first through hole 101, however, the normal block 11 has two first through holes 101. The connection block 13 also has an inner face 130, an outer face 131 opposite to the inner face 130, an upper face 132, a lower face 133 opposite to the upper face 132, a first end 134 and a second end 135 opposite to the first end 134. The upper face 132 also has the base face 1121 and the projection 1122. The lower face 123 also has the groove 1131. The connection block 13 also has the first through holes 101 and the third through holes 102 formed in the projection 1122 and extending from the top face 1122 b to the lower face 133 of the connection block 13.

The first end 134 is a planar face 1341, and the second end 135 is the concave portion 1151, i.e. the concave portion 1151 protrudes inward at the second end 135. When a normal block 11 and a connection block 13 are mated adjacent to each other, the interlocking bond is formed. Precisely, when the tongue 1141 of the normal block 11 is mated with the concave portion 1151 of the connection block 13, the interlocking bond is formed due to the complementary nature of the structure between the tongue and the concave portion. The one or more connection blocks 13 are used to fill small uneven gaps created at the one or more points of termination while constructing the building 900.

The building system 1 further includes a reinforcing element 15 inserted into the first vertical channel formed by the first through holes 101 aligned with each other while a plurality of similar blocks stacked upon each other so that a more secure interlocking interconnection is exhibited. The reinforcing element 15 may be tubular-shaped, and made by hollow metal, plastic or composite material. With such configuration, the reinforcing element 15 may be used as a water supply pipe, a gas supply pipe, a power cable pipe, a communication cable pipe, and so on. The reinforcing element 15 may be shaped to match the first through hole 101, such as a reinforcing rod, which has a diameter smaller than that of the first through hole 101 by 1-2 mm. The reinforcing element 15 is detachable inserted into the vertical channel and can be removed when demolishing the building 900. Thus, the blocks can also be removed with no damage from the building and can be historically reused repeatedly as a new product. As shown in FIG. 17, a plurality of reinforcing elements is used for constructing the building wall. When the building wall is too high, at least two reinforcing elements 15 need to be connected together to be filled into the vertical channel. A connector 151 is used for connecting between at least two reinforcing elements 15, furtherly, the connector 151 is detachably connected between the reinforcing elements 15 so that the reinforcing elements 15 can be detachable while demolishing such building. The connector 151 in different vertical channel are not aligned with each other and are staggered with each other to make the building more firmly.

Preferably, a waterproof glue, a fastening glue, a structural glue, a cement or other adhesive may be applied between each of the interlocking blocks 11, 12, 13 to enhance the strength of the wall of the building.

The building system 1 further includes a plurality of sealing gaskets 16, each of the sealing gaskets 16 is sandwiched between two interlocking blocks, each of the two blocks may be at least one of the corner block 12, normal block 11 and the connection block 13. When the block is stacked upon the cooperating block for constructing the building wall, the sealing gasket 16 is sandwiched between the blocks. The sealing gasket 16 is disposed on the base face 1121 of the upper face 112, 122, or 132 of the block and pressed by the lower face 113, 123 or 133 of the block. With such configuration, the building wall may be waterproof, soundproof, and insulative.

Alternatively, referring to FIGS. 8a-10b , according to a second embodiment of present disclosure, the differences between the first embodiment and the second embodiment are that the second through holes are omitted and a plurality of filling holes are formed in the normal block 21, corner block 22 and connection block 23. Specifically, the normal block 21 further includes at least one filling hole 210 disposed at the side of the projection 1122 and extending from the base face 1121 of the upper face 112 to the lower face 213 of the normal block 21 for accommodating insulating material 211. The filling hole 210 may be cuboidal shaped. The normal block 21 may include a plurality of filling holes 210 spaced apart each other at an equal interval and located at both sides of the projection 1122. When the first through hole 101 is cuboidal shaped, the length of the filling hole 210 in the horizontal direction is greater than that of the first through hole 101.

Similarly, the corner block 22 also has the filling holes 210 disposed at the side of the projection 1122 and extending from the base face 1121 of the upper face 222 to the lower face 223 of the corner block 22 for accommodating insulating material 211. The corner block 22 may include a plurality of filling holes 210 spaced apart each other at an equal interval and located at both sides of the projection 1122. When the first through hole 101 is cuboidal shaped, the length of the filling hole 210 in the horizontal direction is greater than that of the first through hole 101.

Similarly, the connection block 23 also has the filling holes 210 disposed at the side of the projection 1122 and extending from the base face 1121 of the upper face 232 to the lower face 233 of the connection block 23 for accommodating insulating material 211. The connection block 23 may include a plurality of filling holes 210 spaced apart each other at an equal interval and located at both sides of the projection 1122. When the first through hole 101 is cuboidal shaped, the length of the filling hole 210 in the horizontal direction is greater than that of the first through hole 101.

Alternatively, as shown in FIGS. 11-13, according to a third embodiment of the present disclosure, the difference between the first embodiment and the third embodiment is that the second through hole may be disposed at a different position. The plurality of third through holes 102 may be disposed at the side of the projection 1122 and extending from the base face 1121 of the upper face 312 to the lower face 313 of the normal block 31. The plurality of third through holes 102 can be divided into two groups disposed at both sides of the projection 1122, respectively. Each group has at least three adjacent third through holes 102.

Similarly, the corner block 32 also has the plurality of third through holes 102 disposed at the side of the projection 1122 and extending from the base face 1121 of the upper face 322 to the lower face of the corner block 32. The plurality of third through holes 102 can be divided into two groups disposed at both sides of the projection 1122, respectively. Each group has at least three adjacent third through holes 102.

Similarly, the connection block 33 also has the plurality of third through holes 102 disposed at the side of the projection 1122 and extending from the base face 1121 of the upper face 332 to the lower face 113 of the connection block 33. The plurality of third through holes 102 can be divided into two groups disposed at both sides of the projection 1122, respectively. Each group has at least three adjacent third through holes 102.

According to various embodiments of the present invention, when a first block and a second block similar to the normal block 11 are mated adjacent to each other, the interlocking bond is formed. Precisely, when the tongue of the normal block is mated with the concave portion of the second block, the interlocking bond is formed due to the complementary nature of the structure between the tongue and the concave portion. When the first block is stacked upon a second block, each of the first block and second block is at least one of the normal block, corner block and connection block, an interlocking bond is formed by means of the projection 1122 interlocking with the groove 1131. Interlocking the plurality of blocks forms a network of horizontal and vertical channels with the first through holes 101 of the blocks aligned with each other in the vertical direction Z, and the horizontal through holes 14 of the blocks aligned with each other in the horizontal direction X,Y.

FIG. 14 shows the dimensional relation between the normal block 11, the corner block 12, and the connection block 13. A width of the normal block 11 is denoted by W, and a length of the normal block 11 is denoted by L. An outer length of the corner block 12 is denoted by Lco, the dimension Lco is obtained by adding the length L of the normal block 11 to the width W of the normal block 11, i.e. Lco=L+W. An inner length of the corner block 12 is denoted by Lci, the dimension Lci is equal to the length L of the normal block 11, i.e. Lci=L. An outer width of the corner block 12 is denoted by Wco, the dimension Wco is obtained by half of the length L of the normal block 11 adding to the width W of the normal block, i.e. Wco=½L+W; An inner width of the corner block 12 is denoted by Wci, the dimension Wci is equal to half of the length L of the normal block 11, i.e. Wci=½L. A thickness of the corner block 12 is denoted by Tc, the dimension Tc is equal to the width W of the normal block 11, i.e. Tc=W. A length of the connection block 13 is denoted by Lcb, the dimension Lcb is equal to half of the length L of the normal block 11, i.e. Lcb=½L; A width of the connection block 13 is denoted by Wcb, the dimension Wcb is equal to the width W of the normal block, i.e. Wcb=W. It should be understood that the dimension L and W of the normal block 11 can be varied depending on the actual requirement of users. For instance, the dimension L may be 500 mm, and the dimension W may be 150 mm, thus, the dimension Lcb is 250 mm, and the dimension Wcb is 150 mm; the dimension Lco is 650 mm, the dimension Wco is 400 mm, the dimension Lci is 500 mm, and the dimension Wci is 250 mm. According to actual verification, this dimensional relation between the normal block, the corner block and the connection block can guarantee that each building block can be perfectly construct a building without any need to cut them. It should be understood that a dimension allowance is existed while assembling the blocks for constructing the building, the value of the dimension allowance may be ranged from −30 mm to +30 mm, which is varied depending on the size of the gap between two adjacent blocks.

FIG. 17 illustrates the building wall constructed using the normal block 11, the connection block 13 and a plurality of reinforcing elements 15. When the building wall is constructed, at the first layer, a plurality of normal blocks 11 are arranged horizontally side by side, and interlocking bonds are formed with the tongue interlocking with the concave portion of the normal blocks 11. At the second layer, the normal blocks 11 may be offset by half of the length L of the normal block 11 relative to them at the first layer, and connection blocks 13 are filled to the termination ends. The connection blocks 13 and normal blocks 11 are mated adjacent to each other, interlocking bonds are formed with the tongue mating with the concave portion. Interlocking bonds formed between the blocks 11,13 at the first layer and the second layer are formed with the projections 1122 of the blocks 11 at first layer mating with the grooves 1131 of the blocks 11,13 at the second layer. Thus, the third layer can be constructed the same as that at the first layer, and the fourth layer can be constructed the same as that at the second layer. With such configuration, the building blocks can be interengaged securely, which can resist an impact of strong objects and have good anti-seismic effect. The first through holes 101 at the first layer, the second layer and the third layer are aligned with each other to form a plurality of vertical channels for receiving the reinforcing elements 15.

Referring to FIG. 18, a method for producing the building block according to present disclosure is disclosed. The method is described as following: a solid waste J including, but not limited to, industrial solid wastes, domestic wastes, construction wastes, urban sludge, and crop straw wastes, are recovered. Then, putting the recovered solid wastes J into a crushing center A to be pulverized into particles of about 5 mm. A high-water waste K (such as domestic garbage, municipal sludge, etc) is sent to a high-temperature dehydration and elimination center B for high-temperature dehydration, sterilization, and deodorization. A large amount of high-temperature steam I thus obtained would be transported to the high-temperature steam kiln C. Then, the pulverized solid waste L and the dehydrated waste are fed into a stirring center D together with a curing agent, a water repellent, a modifier, a flame retardant, and a binder in a certain ratio, and are thoroughly stirred and mixed. The mixed and stirred materials are sent to the product forming center E to make a building block billet. The billet is fed into the high temperature steam kiln C for high-temperature steaming, and the distilled water H thus produced is sent to the stirring center D for mixing and stirring. After high-temperature steaming, the billet is sent to a facing machining center F to be decorated according to the user's actual requirement and thus, a desired building block is produced. If necessary, the billet will be sealed with composite materials to ensure the physical and chemical properties of the billet stable for a long time. Finally, the building block is sent to the user after being sent to the palletizing packaging center G. However, in the palletizing packaging center G, the product with defect is sent to the product forming center E for repair, and the scrap is sent to the crushing center A for crushing and reused. There is no waste water, waste gas, and waste residue produced throughout the entire manufacturing process.
